Video: Chants of 'Allah-O-Akbar' on Tehran rooftops

GVF -- Chants of Allah-O-Akbar were heard in Tehran last night after the UN Security Council voted in favour of a fresh round of sanctions against Iran over its nuclear programme. Since last June's presidential election, chants of "Allah-O-Akbar" (God is greatest) and "Death to the dictator" have been used regularly by Iranians across the country to voice their protest against their unelected rulers during the night.  It is expected that the chants will become louder as we approach the first anniversary of the election on 12 June.
